摘　　要：随着互联网的发展,边缘宽带接入设备已成为制约网络应用的瓶颈之一。如何加快边缘网络的报文转发处理,提供更好的服务质量(QoS),是当前端到端QoS研究的重要问题。该文介绍了流交换技术,描述了IPv6报文流的处理过程,分析了IPv6的QoS功能,给出了基于IPv6 Flow-Aware的边缘宽带接入路由器的框架结构,定义了相关组件的功能,探讨了面向流的智能报文丢弃策略。With the development of Internet, edge broadband access device is becoming one of bottlenecks restricting network applications. How to forward packets more quickly and provide better quality of service in edge network is very important for end-to-end QoS. This paper introduces the flow switching technology, describes the processing of IPv6 packet flow, and analyzes the QoS features of IPv6. It proposes a frame structure of edge broadband access router based on IPv6 flow-aware and defines the relevant functions of components in router. An intelligent packet discard policy is discussed.
